Discovery of Novel KRAS-PDEδ Inhibitors by Fragment-Based Drug Design
摘要:
[Graphics]Targeting KRAS-PDE delta protein-protein interactions with small molecules represents a promising opportunity for developing novel antitumor agents. However, current KRAS-PDE delta inhibitors are limited by poor cellular antitumor potency and the druggability of the target remains to be validated by new inhibitors. To tackle these challenges, herein, novel, highly potent KRAS-PDE delta inhibitors were identified by fragment-based drug design, providing promising lead compounds or chemical probes for investigating the biological functions and druggability of KRAS-PDE delta interaction.

ionic-liquid-supported tin reagents were synthesized and used in Stillecross-couplingreactions. High yields of biaryls were obtained under low-temperature, solvent-free, ligand-free conditions, with simple purification techniques. Moreover, the tin compound could be recycled up to five times without significant loss of reactivity. An expanded catalytic cycle for the Stille cross coupling reaction is proposed in
Structure-activity relationship of N-[2-(dimethylamino)-6-[3-(5-methyl-4-phenyl-1H-imidazol-1-yl)propoxy]phenyl]-N'-pentylurea and analogs. Novel potent inhibitors of acyl-CoA:cholesterol O-acyltransferase with antiatherosclerotic activity
urea (4), a novel, potent, and systemically bioavailable inhibitor of ACAT (acylCoA:cholesterolO-acyltransferase). The structure-activity relationships (SARs) of this lead compound 4 were investigated by systematic modification of four regions in the molecule. The compounds prepared in this study were tested for in vitro inhibitory activity toward both aortic and intestinal ACATs, and selected compounds
